FVP: apply new naming conventions to memory regions
Secure ROM at address 0x0000_0000 is defined as FVP_TRUSTED_ROM
Secure RAM at address 0x0400_0000 is defined as FVP_TRUSTED_SRAM
Secure RAM at address 0x0600_0000 is defined as FVP_TRUSTED_DRAM
BLn_BASE and BLn_LIMIT definitions have been updated and are based on
these new memory regions.
The available memory for each bootloader in the linker script is
defined by BLn_BASE and BLn_LIMIT, instead of the complete memory
region.
TZROM_BASE/SIZE and TZRAM_BASE/SIZE are no longer required as part of
the platform porting.
FVP common definitions are defined in fvp_def.h while platform_def.h
contains exclusively (with a few exceptions) the definitions that are
mandatory in the porting guide. Therefore, platform_def.h now includes
fvp_def.h instead of the other way around.
Porting guide has been updated to reflect these changes.
